I This invention relates to apparat-us" for extracting the Wire cores usually provided: inthebeads,

rims or straps of tires and for extracting" wire cores embedded in other material in; a similar way. In other words, itrelates to apparatus for the recovery of cores embedded in surroundin bodies.

The recovery of: such wire cores is important because the salvaged materials. can be reutilized for similar or other purposes.

A principal object of the invention is: to provide apparatusv that. will make salvage operations simple and effective.

Another object of the invention isto: provide apparatus that is comparatively simple: in construction and effective forthe' purposes intended.

Another object of theinventionisto provides a novel method of extracting cores from theirsurrounding bodies.

To the accomplishment of" the foregoing andsuch other objects' as mayhereinafter appear,

this invention consists in:thenvel method, construction and arrangement of: partshereinafter to be described and then sought to bedefined in the appended. claims, reference beinghadtot-he accompanying drawing: forming a part. hereof, which shows, merely for the purposesof illustrative disclosure, a preferred embodiment ofthe invention, it being expressly understood, however, that changes may be made in practice withi-n the scope of the. claims without digressing, from, the

inventive idea.

In the drawing in whichsimilar. reference characters denote corresponding parts:

Fig. 1 is a perspective view ofpart of the apparatus utilized;

Fig. 2 is a plan view of the apparatus of Fig. 1;

Fig. 3 is a perspective view of another piece. of apparatus used in the extraction. of the wire cores; and

Fig. 4 is a fragmentary elevational' view of a hooked instrument used in conjunction with other parts of the apparatus in the extraction of wire cores.

In the extraction of the. Wire. cores from the rims or straps which havealready been separated from the tires, or for. the extraction of wire or other cores embedded in a surrounding, body of other material in a similar way, itisafirst necessary to make cuts or incisions intothe body of material surroundingthe: Wire cores or rings in order toreach the cores or rings and thereafter to spread or open thecuts-or incisions in asuitable press or vise to expose the cores-or rings so that th y m y be emo d with conventional.

utilized to make the necessary cuts or incisions into: the soft body. The apparatus of- Fig. 3;- is a. press or vise that-is used tospreadthe'incisions so that the. aforesaid hooked instrument can be utilized to pull the cores out of their bodies.

The apparatus of Figures 1 and 2; include a supporttable It). This table isprovided suitably with a movable carriage or car l-l'. Bearings 12- are provided.on-the-carriage I I and: these in turnsupport a, rotatable shaft l3 which carries a; drum pulley: 1.4. 01 the like. Ifhe shaft l3' (and with it the pulley I4) is freely rotatable in the bearings; 12. The. carriage H maybe moved reciprocallyin itsguideway IB-inany well known way, for example by the worm or screw l6 and hand wheel l1.

A second shaft l8 extending parallel with thel shaft I3 issupportedinthe bearings; |9.-tha t are suitably attached. tothe support table NJ;v A- transmission gear- 20' is attached to. the shaft I8 and meshes with the driving pinion 2:! (Fig. 2) of a suitablemotor 2-2 sothat the shaft l8 may be driven or rotated. A drum pu11ey23or the likeis fixed-t0 the-shaft [8. Teeth 24' are provided on-t-he said pulley 23. These teeth, however, may bereplaced-by other suitable means, for example; aroughened surface; that will serve. to provide necessary frictionfor driving the endless'straps or the rimsB' (Fig.2) which are to be carried on the pul1eys M1 and 2 3= during cutting opera-- tions'presently to be described. The pulleys: I4- and: 231 are: supported in lateral alignment, and manipulation of the hand.- wheel H effects movement -of pulley. l4; withits carriage: H toward or away from pulley 23- for apurpose to bepresently: described;

A second support table 25 is provided: in 0011- junction with: the" table: I0; This table may; be integral with table "1- or if separate is preferablyimmovable' with respect tothetable II); Such immovability may be'provided in any suitable manner, for example, t by the massiveness" of the weights of the. table's lfl'and 25. or by-actualphysi calattachment. A reciprocally movable carriage 26 is slidably'supportedin a'suitable guideway 21' provided on the table' 25: Thisycarriage' 26 may" be moved reciprocally in its'guide-Way 2! in any. welllknowni manner; for example; .by the-screw 28* and: hand wheel 29:

The guide-way 2 T? is so: ar-" ranged on table that carriage 26 is movable reciprocally in a direction parallel with that of carriage A guideway 30 is provided in the carriage 26 which extends transversely of the direction of the guideway 21. A carriage 3| is slidably supported in this guideway 30. This carriage 3| may be moved reciprocally in its guideway 33 in any well known manner, for example, by screw 32 and hand wheel 33.

A tool holder block or support 34 of an conventional type is suitably supported on the 'carriage 3|. This tool holder block 34 accommodates one or more tool holders 35 of conventional type. Individual set screws 36 serve to clamp individual ones of the tool holders with respect" to the block 34 in well known manner.. Chisels,

knives or other cutting tools or elements, 31 are suitably supported on the tool holders 35. These cutting elements 31 may be individually adjusted or removed from the respective" tool holders, in

conventional manner. 7

It'will be seen that the provision of the two carriages 2B and 3| which are movable at right angles to each other by manipulation of the respective handwheels 29 and 33 permits two directional adjustments of the tool holder block-34 andconsequently of thetool holder or holders 35 carried thereby so that both depth of cut and location of cut by cutting element or' elements 31 can be efiected. 7 I

In operation of the apparatus thus far described, one or more of thew'irecored rimsior straps previously removed from tires, or other cored straps whichare in the form of endless l bands B (Fig. 2) are-placed upon the two pulleys l4 and 23. The hand wheel I1 is then manipu lated to move carriage II and with it pulley l4 away from pulley 23 to tension the bands on The motor 22 is then started and the bands are driven around the pul the pulleys l4 and 23.

each band bracing itself against another. "The problem of handling the beads, removed from old tire carcasses, has caused those skilled in the art to use elaborate machines for removing the tire wire from the beads prior to severing'the latter from the'tire carcasses. As just describedjthe present invention solvesthis problem.

The hand wheels 29 and 33 are then manipulated so as to properly position" the'cutting edges of the cutting tool or tools 31 with respect tothe moving surfaces of the pulley-mounted, wirecored rims or straps so as to cut into the'soft bodies thereof. The position of the cuts on the straps or bands is regulated by manipulation 'of hand wheel 33, while the depth of cut or incision is regulated by manipulation of hand wheel 29.

The number of cutting tools 31 utilized at once depends upon the dimensions of the wire cored rims or straps and the number thereof mounted as bands on the pulleys |4 and'23 at anytime. After the cutting tool or tools 31 have been adjusted for position by hand wheel 33 the depth of -.cut is adjusted by hand'wheel 23Cand is 311. 011

' employed.

creased thereby until the cutting edge or edges of tool or tools 31 reach the wire cores in the body or bodies of the bands B. The incision or cuts in the body, of course, are continued until they extend substantially over the entire periphery of the endless rim or bands to the depth of the wire core. Then the cutting tools 31 are withdrawn, the motor 22 stopped, the pulley |4 moved toward pulley 23 and the so out or incised rims or straps removed from the pulleys M and 23.

Since the body of material surrounding the wire cores usually includes rubber or other resilient material thecuts or incisions tend to close and must be spread apart to expose the wire cores so that a hooked instrument 39 may be inserted to engage the Wire core, so that the latter may be stripped from its surrounding body.

To this end a suitable clamp or'vise may be utilized. For example the vise or clamp shown in Fig. 3 may be utilized. This vise comprises a fixed jaw 40, a movable jaw 4| and teeth 42 and 43 on the faces of the jaws 40 and 4|. The fixed jaw 40 is supported on a. suitable fixed base 44. The movable jaw is slidably carried on a suitable support 45 by its guide portion 46, the latter extending through a suitable guideway 41 provided in the body of the fixed jaw 40. Any other conventional means for guidedly supporting the movable jaw 4| relative to the fixed jaw 40 may be The movable jaw 4| is moved toward and away from the fixed jaw- 40 in any conventional manner, for example, by use of the screw 48 and manipulating handle 49, in well known manner.

In use the rims or straps that have been pre-.

viously cut or incised as hereinbefore described are placed between'the jaws 40 and 4|. Jaw 4| is then moved toward jaw 40 to clamp a portion of the body of the previously incised rim or strap between the jaws.

The clamping action causes the teeth 42 and 43 to grip the soft body of the core and to spread the-cuts inthe upper surface of the rims'or straps. The hook end 39' of the hooked instrument 39 is then inserted into the spread incisions or cuts and the wire core or ring stripped from the surrounding body.

It is to be understood that the apparatus is capable of use for extraction of cores other than wire from soft surrounding bodies.
